My invention relates to an improved radiator for heating, which can be used for domestic or any other purpose, where coinpact heating device is required with perfect safety from lire. It has for its object to provide a. radiator which is more cl'licient and more rapid in its action than types at present in use, and is a portable or rigid ure as desired, for use in any place or position where 16 naked light or flame as a source of heat is undesirable.

According to my invention I. employ a radiator block for dis outing the heat substantially of the type utilized in motor car radiators for the purpose of getting rid ot the heat iin artcd to the cooling water of the engine. Such a block comprises a number of thin metal tubes secured together so as to form a, honeycomb or cellular block having a 20 number of lateral air passages through it each more or less surrounded bya thin channel through which the heated water may circulate, an electric or other suitable heating device being provided in, or in the vicinity of, the space accommodating the water.

In constructing the block for my improved radiator I prefer to employ tubular elements. The tubes are preferably arranged so that the air spaces through the block instead of extending horizontally from back to front of the radiator are inclined at a substantial angle thereto so as to produce natural currents of air through them and thus add to the effective circulation of heated air in the room or compartment in which the radiator is employed.

The radiator block is arranged in a suitable casing which may conveniently be made of sheet material and is provided with a. lower compartment incorporating the means tor heating the water or other circulating n'iedium, and passages extend up from this lower compartment along the sides of he radiator to a space at the top of the radiator from whichthe liquid enters the channels in the block and so return to the lower compartment where it will be heated again. in this manner a continuous thcrmo-siphon circulation will. be maintained. Any suitable heating means may be employed for heating the Serial No. 291,869.

niudrical or tubular form. is provided in one end of the compartment through which the elementmay be inserted and by winch it is fixed in a position so as to make a liquid-tight connection with the casing. For this purpose a suitable circular boss may be provided on the end of the easing of the lower compartment having an aperture siimcieiit to allow the electrical element to be inserted through it. The element may be secured in position by providing a screw-threaded flanged member at one end thereof adapted to engage in a screwthread in a hole in the boss and be tightened up so that the flange will make a tight joint against the boss or with suitable packing material placed between them. A suitable fill ing and vent aperture may be provided on the top portion of the casing.

In order that my invention may be clearly understood and readily carried into effect I have appended hereto a sheet of drawings illustrating an embodiment of same and so wherein Fig. 1 is a front elevation;

Fig. 2 is a sectional side elevation on the line A-B of Fig. 1.

Fig. 3 is a detail sectional front elevation to a larger scale showing part of the lower end of the radiator, ano the heating device, and

Fig. 4 is a detail sectional View of the preferred form of filling cap combined with a pressure relief valve.

Referring to the drawings the radiator illustrated is suitable as a portable device which can be carried from one room to another, and has a suitable electric plug connector 1 whereby it may be readily connected to a source of electric current for supply ing current to suitable resistance elements carried by an electrical heating device 2, which as shown is preferably immersed in 1 the water contained in the radiator to ensure efficient heating. The radiator can be of any suitable configuration but is shown as a rectangular body'having outer enclosing walls 3, the vertical walls of which have narrowly spaced from them the vertical walls l of a honeycomb radiatorv 5, the lower part of which is spaced sufficiently from the lower wall 3 to provide a-compartment 6 providing ample accommodation for the heater 2 and the water.

The narrow cells around the openings the radiator communicate with the narrow vertical spaces 8 between the vertical walls 3 p and 4, restricted passages 9 being provided in the walls 4 for this purpose,relongatcd narrow openings also being formed in the lowermost and uppermost of said narrow cells for communicating with the space 6, and the space 10 between the upper end of the honeycombed structure and the upper wall 3. The vertical spaces 8 provide an easy passage for the ascending hot water, the water in the narrow cells of the radiator block being more exposed to the effect of the outside. air becom- 111 cool morera idl and conse uentl de- 'scending to the chamber 6, thereby establishdate a pressure relief valve, which as shown in a can be a spring loaded ball valve 13 accommodated in a central integral boss 14 of the cap 11, a cap 15 having a suitable vent 16 holding the spring 17 in position.

The heating element 2 1s carrled by aninsulating plug 18 which can befitted in a collar 19'th'readed intoa boss 20 at one end of the chamber 6. An-insulating cover 21 is preferably fitted over the terminals of the plug 18.

A radiator according to my invention suitable for domestic or commercial heating purposesmay be constructed in a much more compact form than the existing type of cast iron radiators or others in use, and will have'a greater efiiciency. Owlng to the comparatively small'in'ass of the radiator itself and of the liquid contents being spread over a much greater area of the honeycomb, an ef-' fective heating temperature can be more quickly obtained, thus enabling a room to be heated up at short notice and without having to wait for long period before obtaining the desired degree of warmth.

A radiator comprising an open frame, a

plurality of cells inclined relative to the hori- Toff zontal plane and open at both ends passing transversely through said frame, hollow ver-- tical walls forming the ends of said frame, a water chamber with an inclined base at the top of the frame bridging and communicating with the upper ends of said hollow vertical walls, a water chamber with an inclined top in the base of said frame bridging and communicating with the lower ends of said hollow walls, water flow openings in the vertical walls communicating with said cells, an electric heater in the lower water chamher, and a filler cap in the upper water chambar. 7
